A Z r INVENTOR My mommm 4% miazzr" Patented Feb. 14, 1933 UNITED STATESPATIENT OFFICE JOHN M. OLDHAM, OF DETROIT, MICHIGAN, ASSIGNOR TO L. A.YOUNG SPRING & WIRE CORPORATION, OF DETROIT, MICHIGAN SPRING STRUCTUREApplicationfiled January 29, 1932. Serial No. 589,597.

The main object of this invention is toprovide a spring structure forbeds, cushions, mattress fillers and the like in which the bordersprings are effectively supported in upright position and maintained 111properly spaced relation.

A further object is to provide a structure having these advantages whichis economlcal in its parts and easily assembled.

Objects pertaining to details and economies of my invention willdefinltely appear from the description to follow. The invention isdefined in the claims.

A structure which embodies the features of my invention is clearlyillustrated in the accompanying drawing, in which:

Fig. l is a fragmentary plan view of a spring structure embodyingfeatures of my invention.

Fig. 2 is an enlarged fragmentary perspective view showing structuraldetails.

Fig. 3 is a perspective view of one of the combined spacing and lockingmembers.

The embodiment of my invention illustrated comprises a border frame 1preferably of light rod or heavy wire, and a plurality of helicallycoiled body springs 2, these being shown conventionally and the bottomsupport being omitted. The springs are con nected by the crossed helicalsprlng ties 8. The outer body springs are arranged with their end coilsadjacent the border frame to which they are secured.

The connection consists of the U-shaped sheet metal clips 4: arrangedwith their bights embracing the border frame and their arms embracingthe adjacent coils of the border or outer springs. These clips havealined holes 5 in their arms disposed so that the hooks 6 of the spacingmembers 7 can be passed through the holes at the inner side of or withinthe adjacent spring coils, thereby locking the border springs to theborder frame and at the same time supporting these border springs inproper spaced relation, the spacing members connecting adjacent pairs ofclips.

With this arrangement of parts the outer body springs are very securelyconnected to the frame and held in proper spaced relasprings disposedwith coils thereof adjacent said border frame, U-shaped clips embracingsaid border frame and said spring coils disposed adjacent thereto, thearms of the clips having alined holes therein, and spacing membershaving hooks at their ends disposed through the holes of adjacent clipsand within the spring coils, thereby supporting the springs in spacedrelation and securing them to the border frame.

2. In a spring structure, the combination with a border frame, aplurality of body springs disposed with the coils thereof adjacent saidborder frame, U-shaped clips embracing said border frame and said springcoils disposed adjacent thereto, the arms of the clips having alinedholes therein lying within the confines of the end coil of the borderspring that the clip secures to the border frame, and spacing membershaving their ends disposed through said holes to secure the springs tothe border frame and support them in spaced relation.

3. In a spring structure, the combination with a frame, a plurality ofbody springs disposed with coils thereof adjacent said frame, clipsembracing said frame and said spring coils disposed adjacent thereto,the arms of the clips having alined holes therein lying within theconfines of the end coil of the spring that the clip secures to theframe, and spacing members having their ends disposed through said holesto secure the springs to the frame and support them in spaced relation.

In witness whereof I have hereunto set my hand.

JOHN M. OLDHAM.
